Prosecutors on Wednesday charged a Puyallup-area man with four crimes after he allegedly supplied the marijuana extract his daughter is believed to have used to bake brownies she later gave to classmates, sickening some of them.

Not guilty pleas were entered on behalf of Michael Dennis Miller, 45, to two counts of unlawful manufacture of a controlled substance and one count each of unlawful delivery of a controlled substance to a person under 18 and reckless endangerment.

His 16-year-old daughter is charged as a juvenile with three counts of unlawful delivery of a controlled substance. She’s pleaded not guilty.

Sheriff’s deputies began investigating Miller on Tuesday after officials at Emerald Ridge High School reported that four students had taken ill after his daughter gave them baked goods.

A deputy dispatched to the school said four students “reported having symptoms including being shaky, numb, anxious, fuzzy and sick,” charging documents state. “Aid personnel reported that one student had an elevated heart rate and blood pressure.”

The deputy seized a container of brownies and lemon bars from Miller’s daughter. She first said she’d gotten the goodies at a weekend party but later said she’d baked them at home using “coconut THC oil” she’d gotten from her father, court records show.

Investigators went to her home where they found evidence of a marijuana-growing operation and a hash-oil extraction lab, the records show.

Miller, who returned home while deputies were raiding his house, told them he had a medical-marijuana authorization card, but was unable to find it, court records show.

He admitted to extracting hash oil from marijuana in the presence of his children and said he allowed them to smoke marijuana, charging papers state.

Miller told investigators he knew his daughter was making THC-laced foods but did not know she planned to take them to school, the records state.
